Bibliography Formatter

What the Bibliography Formatter Does

The Bibliography Formatter turns the details of a source into a correctly styled bibliography entry. Enter the authors, year, title, and publisher or container, choose APA 7th edition, MLA 9th edition, or Chicago 17th edition, and the tool produces a formatted entry with the right punctuation, italics, and author name order. Add as many entries as you need and the full bibliography is sorted alphabetically, ready to copy into your paper.

Everything happens locally in your browser. Your sources are never uploaded, and the formatted list updates instantly as you change the style from APA to MLA or Chicago.

How to Build a Bibliography

1. Pick the source type: book, website page, journal article, or online video.
2. Enter the authors, year, title, and the publisher, website, journal, or platform. Add volume, issue, pages, edition, and a URL or DOI when they apply.
3. Press Add entry. The preview on the right formats the entry immediately.
4. Repeat for every source. Entries are sorted alphabetically by the first author's last name, or by title when there is no author.
5. Change the style selector to switch the whole bibliography between APA, MLA, and Chicago, then copy the plain text version.

How the Three Styles Differ

The three major styles organize the same information in different orders. A book entry shows the difference clearly:

• APA 7th edition: Author, A. A. (Year). Title of the book. Publisher. APA puts the year right after the author in parentheses and uses initials, and the list is sorted by author surname.
• MLA 9th edition: Author, First. Title of the Book. Publisher, Year. MLA uses full first names, puts the author's surname first, and puts the publisher before the year.
• Chicago 17th edition: Author, First. Title of the Book. Publisher, Year. Chicago bibliography entries are similar to MLA but use headline style capitalization and a period instead of a comma between publisher and year.

Websites, journal articles, and videos follow the same pattern with one extra layer: the container. In MLA and Chicago, article and page titles appear in quotation marks while the journal, website, or platform name is italicized. In APA, the same split applies but the year moves up next to the author.

Author Name Rules

Author order is one of the easiest things to get wrong. This tool reformats names automatically:

• APA: "Doe, Jane" becomes "Doe, J." In-text and reference list, APA uses surnames and initials for every author, with an ampersand before the final name.
• MLA: the first author is listed surname first ("Doe, Jane") and later authors are not ("Alex Smith"). The whole list joins with "and" before the last name.
• Chicago: the first author is inverted and later authors are not, matching the bibliography pattern used by the notes and bibliography system.
• Many authors: MLA switches to "et al." after three authors and Chicago lists up to ten before switching to "et al." This tool follows both rules.

Enter authors separated by semicolons, like "Doe, Jane; Smith, Alex". Both "Doe, Jane" and "Jane Doe" formats are understood, so you can paste names the way you already type them.

Sorting and Hanging Indents

Every serious style guide requires an alphabetically sorted list with a hanging indent, meaning the first line starts at the margin and any following lines are indented. The tool sorts entries by the first author's surname, falls back to the title when no author is given, and shows the preview with a true hanging indent. The plain text version keeps one blank line between entries so it pastes cleanly into Word, Google Docs, or any editor where you apply the hanging indent paragraph setting.

When to Use Each Style

• APA: psychology, education, social sciences, and most health and nursing programs.
• MLA: English literature, languages, cultural studies, and other humanities writing.
• Chicago: history, art history, music, and many book publishing contexts. Chicago has two systems, and this tool follows the notes and bibliography style most often used in the humanities.

When in doubt, check your assignment brief or the journal's author guidelines. Some instructors adapt the rules, so their instructions always win.

Common Bibliography Mistakes

• Using commas between publisher and year in APA, where APA wants a period and the year belongs right after the author.
• Leaving article titles italicized. Only the journal or container name is italic, and in MLA and Chicago the article title goes inside quotation marks.
• Sorting by first name or title. Sorting always follows the surname of the first author.
• Forgetting the access URL for online sources when the style requires it, or leaving a trailing period after a URL in styles that omit it.
• Mixing initials and full names. Each style is consistent: APA uses initials, MLA and Chicago use full names.

Privacy

Sources are formatted entirely in your browser with no server round trips. Your reading list, notes, and citation details never leave your device, which matters when you are working with unpublished or confidential material.
